Cummins Oil Pumps for KTA19 Engines

High-Volume Oil Pump for KTA19 Series

The oil pump is the heart of the KTA19’s lubrication system, responsible for circulating oil through the engine block, bearings, camshaft galleries, piston cooling jets, and turbocharger feed lines. Diesel Pro Power offers a factory-grade oil pump compatible with a wide range of CPL configurations for the KTA19, KT19, and QSK19.

• Applications: Compatible with multiple CPL configurations
  
  

• Design: Gear-type oil pump with high flow rate
  
  

• Function: Provides constant oil pressure to main, rod, and cam bearings
  
  

• Build: Cast iron housing with precision-ground steel gears
  
  

• Ideal For: New builds, complete overhauls, and correcting low oil pressure issues
  
  

Installing a new oil pump is recommended during any major rebuild, especially if oil pressure readings have declined or if bearing surfaces show signs of wear due to lubrication failure.

Oil Coolers for Cummins KTA19 and QSK19

Dual Oil Cooler Configuration

Cummins KTA19 engines utilize two oil coolers per engine to maintain optimal oil temperature and prevent viscosity breakdown under extreme operating conditions. Diesel Pro Power offers both oil cooler units required for a complete setup.

• Cooling Method: Water-to-oil heat exchange
  
  

• Application: Marine and high-load stationary engines
  
  

• Quantity Required: 2 per engine
  
  

• Compatibility: KTA19, QSK19, KTA38, and KTA50 models
  
  

By maintaining proper oil temperature, the coolers help prevent thermal damage to bearings and reduce carbon buildup in oil passages. Routine inspection and replacement are essential in marine environments where corrosion can degrade cooler effectiveness.

Oil Cooler Gaskets and Seals

Diesel Pro Power stocks a full selection of oil cooler sealing components, including:

• Oil cooler cover gaskets – Seals the top-side housing where oil flows into the cooler
  
  

• O-rings for oil cooler cores – Ensures leak-free seating between cooler and block
  
  

• Oil cooler housing gaskets – Critical for resealing after cooler service or replacement
  
  

These components are often overlooked during cooler servicing but are essential for preventing oil and coolant leaks. Replace gaskets and O-rings every time the cooler is removed to ensure system integrity.

Marine Zinc Anodes for Oil Coolers

To protect your oil cooler from internal corrosion in saltwater applications, Diesel Pro Power offers zinc anodes designed for Cummins marine engines.

• Thread Size: 3/8” NPT brass plug
  
  

• Zinc Length: 1 inch
  
  

• Function: Sacrificial corrosion protection for fuel and oil cooler cores
  
  

• Application: Marine-only systems
  
  

Installing fresh zincs as part of your regular maintenance routine extends the service life of your oil cooler and prevents damage from electrolysis.

Oil Filters and Related Tools

Spin-On Oil Filter for Cummins KTA19

Oil filtration is critical in removing contaminants that can degrade bearing surfaces and accelerate engine wear. Diesel Pro Power provides high-capacity spin-on oil filters compatible with the KTA19 platform.

• Thread Type: Standard 2 1/4” - 12 UN
  
  

• Size: 4.65” diameter x 11.69” height
  
  

• Filtration Media: High-density cellulose/synthetic blend
  
  

• Use Case: Daily operation, extended-service maintenance intervals
  
  

Spin-on filters are quick to replace and should be changed with every oil change or as specified by your engine's service interval.

Oil Filter Removal Wrench

To streamline oil filter service, Diesel Pro Power offers a professional-grade oil filter wrench designed to fit filters between 4-21/32” and 5-5/32” in diameter. It is compatible with Cummins, Detroit Diesel, and Caterpillar engines.

• Grip Range: Adjustable for multiple filter sizes
  
  

• Build: Heavy-duty steel strap design
  
  

• Use Case: High-torque removal in confined spaces
  
  

Using the correct wrench ensures safe, damage-free removal and reduces service time during routine oil changes.

Oil Pan and Adapter Gaskets

Oil Pan Adapter Gasket

Diesel Pro Power offers a high-quality oil pan adapter gasket for the lower portion of the KTA19 crankcase. This gasket seals the interface between the oil pan and the block or pan adapter plate.

• Material: High-temperature oil-resistant composite
  
  

• Use Case: During oil pan removal, leak repair, or bottom-end rebuilds
  
  

• Fitment: KTA19 and QSK19 compatible
  
  

Replacing this gasket is essential when resealing the lower crankcase after a crankshaft service, oil pump replacement, or pan cleaning.

Hand Hole Cover Gaskets

The hand hole covers located on the engine block allow internal inspection of the crankcase and connecting rods. Diesel Pro Power stocks the matching cover gaskets to reseal these inspection ports.

• Function: Seals access holes to prevent oil leaks and contamination
  
  

• Recommendation: Replace any time the hand hole cover is removed
  
  

• Use Case: Crankshaft inspection, connecting rod bearing service
  
  

These small gaskets play a critical role in maintaining crankcase cleanliness and pressure balance.

Oil Pressure Monitoring Components

Oil Pressure Switches – Make/Break Configurations

Accurate oil pressure readings are vital for engine protection and early diagnostics. Diesel Pro Power carries a range of make/break pressure switches in 5, 10, 20, and 27 PSI ratings.

• Use Case: Triggers alarms or shutdowns based on oil pressure threshold
  
  

• Thread Type: 1/8” NPT for universal fit
  
  

• Electrical Interface: Make/break function engages or disengages based on pressure
  
  

• Compatible Engines: Cummins and Detroit Diesel platforms
  
  

These switches are commonly installed in marine engines, generator sets, and industrial units to prevent catastrophic engine failure due to oil pressure loss.

Gauges for Oil System Monitoring

Mechanical and Electric Oil Pressure Gauges

Diesel Pro Power offers a wide selection of oil pressure gauges to pair with your pressure switches or to monitor oil system performance independently.

• Mechanical Gauges: Provide direct pressure readings without electrical input
  
  

• Electric Gauges: Available in 12-volt and 24-volt configurations
  
  

• Gauges with Alarm: Built-in sensors trigger audible or visual warnings
  
  

Whether retrofitting a dashboard or building a custom engine panel, we offer gauges compatible with your existing sensors and pressure ranges.

Why Proper Oil System Maintenance Matters

The Cummins KTA19 is a high-output engine that depends on consistent lubrication and oil temperature control. Key functions of a properly maintained oil system include:

• Lubrication of bearings, gears, and piston skirts
  
  

• Oil-based piston cooling via jets beneath the pistons
  
  

• Turbocharger lubrication and cooling
  
  

• Hydraulic control of valve actuators (in certain versions)
  
  

• Debris and particulate removal via filtration
  
  

Neglecting the oil system can lead to:

• Premature bearing wear or failure
  
  

• Crankshaft or camshaft scoring
  
  

• Turbocharger damage
  
  

• Overheating due to insufficient oil cooling
  
  

• Severe oil leaks leading to rapid oil loss
  
  

Replacing worn components such as pumps, seals, gaskets, and filters at regular intervals is a cost-effective way to prevent catastrophic failures and extend engine service life.

Troubleshooting Common Oil System Issues

Low Oil Pressure

• Possible Causes: Worn oil pump, clogged pickup, leaking pressure switch, worn bearings
  
  

• Solution: Replace oil pump, check bearing clearances, confirm switch and gauge function
  
  

Oil Leaks at Cooler or Filter

• Possible Causes: Worn O-ring or gasket, damaged cooler housing
  
  

• Solution: Replace all cooler gaskets and O-rings during service, inspect housing surfaces
  
  

Overheating or Oil Breakdown

• Possible Causes: Restricted oil cooler, marine zinc corrosion, insufficient oil flow
  
  

• Solution: Replace oil coolers, flush cooling system, inspect zincs for degradation
  
  

Inaccurate Gauge Readings

• Possible Causes: Faulty sender, bad electrical ground, incorrect gauge calibration
  
  

• Solution: Test sender with manual gauge, verify wiring, replace with matched sensor and gauge
  
  

Best Practices for Oil System Service

1. Use manufacturer-approved oil grades and intervals
   
   

2. Replace oil filters with every oil change
   
   

3. Flush oil coolers during major service
   
   

4. Inspect zincs quarterly in marine applications
   
   

5. Replace gaskets and O-rings whenever parts are removed
   
   

6. Install new hand hole cover gaskets after internal inspections
   
   

7. Test oil pressure switches annually
   
   

8. Monitor gauge readings daily on high-hour applications
